Technical Field
[0001] This application relates to the field of traffic facility testing technology, and in particular to a device for testing the center height of a traffic safety guardrail crossbeam. Background Technology
[0002] A device for testing the center height of the crossbeam of a traffic safety guardrail is an important part of the testing of traffic safety guardrails. It is used to measure the center height of the designed crossbeam, that is, the height from the road surface as the starting point to the middle position of the corrugated beam of the crossbeam.
[0003] In related technologies, when testing the center height of the crossbeam of a traffic safety guardrail, the tester is positioned on one side of the center area of the crossbeam and stretches a steel tape measure straight from the ground. A spirit level is then placed horizontally at the middle of the crossbeam before the height data is read.
[0004] In the aforementioned related technologies, the method for testing the center height of the crossbeam of a traffic safety guardrail requires two operators to perform the measurement. The inventor believes that there is a need to provide a device for testing the center height of the crossbeam of a traffic safety guardrail that is convenient for a single operator to perform. Utility Model Content
[0005] To facilitate individual operators in testing the center height of traffic safety guardrail diaphragms, this application provides a device for testing the center height of traffic safety guardrail diaphragms.
[0006] This application provides a device for testing the center height of a traffic safety guardrail diaphragm beam, which adopts the following technical solution:
[0007] A device for testing the center height of a traffic safety guardrail crossbeam includes a main ruler and a laser test piece. The main ruler is made of magnetic material. The main ruler has a placement plane on the ground and a first measuring plane perpendicular to the placement plane for the laser test piece to be moved around. The first measuring plane is provided with a first scale structure. The laser test piece includes a test piece body, a laser emitter disposed at the front end of the test piece body, a measuring and leveling structure disposed on the test piece body, and a magnet structure installed on the test piece body and used to attract the main ruler. When the measuring and leveling structure is in a horizontal state, the laser emitted by the laser test piece is in a horizontal direction.
[0008] By adopting the above technical solution, when operators use the aforementioned traffic safety guardrail diaphragm center height testing equipment to test the center height of the diaphragm, they first place the main ruler on the ground, directly opposite the center of the diaphragm. Then, they adjust the height of the laser test piece and keep the leveling structure horizontal, ensuring the laser beam emitted is horizontal. When the laser point falls on the test point, the center height of the diaphragm can be obtained by reading the corresponding position of the laser test piece and the first ruler structure. This traffic safety guardrail diaphragm center height testing equipment is convenient for a single operator to perform, and offers more ideal testing accuracy.
[0009] Optionally, the magnet structure includes at least one of the first magnets.
[0010] Optionally, the magnet structure includes two first magnets, which are arranged at intervals along the length of the test piece body.
[0011] By adopting the above technical solution, two first magnets are set on the laser test piece, which helps to ensure that the laser test piece is attracted to the first measuring plane of the main scale body and helps to reduce the probability of the laser test piece falling off the main scale body.
[0012] Optionally, the magnet structure includes a first magnet and a second magnet, wherein the magnetic strength of the first magnet is higher than that of the second magnet.
[0013] By adopting the above technical solution, a first magnet and a second magnet with different magnetic strengths are set on the laser test piece, so that the first magnet with higher magnetic strength can be used as the rotation point. Then, by adjusting the part of the laser test piece in which the second magnet is installed, it is easy to level the laser test piece.
[0014] Optionally, the main scale body has a first through groove along the height direction on the first measuring plane, the test piece body has a guide protrusion that is slidably arranged in the first through groove, and the end face of the guide protrusion has a first arrangement groove for arranging the first magnet; the test piece body is also provided with a second arrangement groove for arranging the second magnet.
[0015] By adopting the above technical solution, the guide protrusion in the laser test piece is arranged in the first through groove, which can guide the laser test piece in terms of height position adjustment. In addition, during the leveling process of the laser test piece, the cooperation between the guide protrusion and the first through groove prevents the laser test piece from moving horizontally, thereby facilitating the leveling operation of the laser test piece.
[0016] Optionally, the first scale structure is arranged on the back side of the measuring plane, and an indicator tip is provided at the tail end of the test piece body.
[0017] By adopting the above technical solution, an indicator tip is set at the tail end of the test piece body, which helps the operator read the data on the first scale structure.
[0018] Optionally, the top surface of the main ruler body is a first top surface parallel to the placement plane, and a placement leveling structure is provided at the first top surface.
[0019] By adopting the above technical solution and setting up a leveling structure, it is helpful to level the main scale body, thereby reducing the probability of inaccurate measurement data caused by the main scale body not being leveled.
[0020] Optionally, the main scale body has a secondary scale hole on its top surface along the height direction, and a secondary scale body is slidably arranged at the secondary scale hole; the main scale body is also provided with a locking structure to lock the secondary scale body in the secondary scale hole; the secondary scale body is made of magnetic material, the secondary scale body has a second measuring plane for arranging the laser test piece, and the secondary scale body is provided with a second scale structure at the second measuring plane.
[0021] By adopting the above technical solution, the addition of a secondary ruler helps to increase the testing range of the traffic safety guardrail crossbeam center height testing equipment. Furthermore, the locking structure locks the secondary ruler within the secondary ruler hole of the main ruler and allows the laser test piece to be placed on the second measuring plane of the secondary ruler, thereby obtaining data on the center height of the traffic safety guardrail crossbeam.
[0022] Optionally, the locking structure includes a locking screw hole formed in the main scale body and communicating with the outer wall of the main scale body and the secondary scale hole, and a locking bolt threaded into the locking screw hole.
[0023] By adopting the above technical solution, the specific structure of the locking structure is disclosed. The locking bolt is used to lock the auxiliary scale body in the auxiliary scale hole, and the stability of the above locking mechanism is relatively ideal.
[0024] Optionally, the locking bolt head is provided with a tightening handle.
[0025] By adopting the above technical solution, tightening the handle helps the operator rotate the locking bolt, thereby facilitating the operator to control the locking structure and adjust the height position of the auxiliary scale body in the auxiliary scale hole.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. A device for testing the center height of a traffic safety guardrail crossbeam, comprising a main scale and a laser test piece, wherein the center height of the crossbeam is obtained by adjusting the position of the laser test piece on the first measuring plane of the main scale, which facilitates a single operator to test the center height of the traffic safety guardrail crossbeam and provides more ideal testing accuracy;
[0028] 2. By setting the magnet structure in the laser test piece as a first magnetic block and a second magnetic block, and the magnetic strength of the first magnet is higher than that of the second magnet, the leveling operation of the laser test piece is facilitated.
[0029] 3. By opening a secondary scale hole on the main scale body and setting a secondary scale body inside the secondary scale hole, it is helpful to increase the testing range of the traffic safety guardrail crossbeam center height testing equipment. Attached Figure Description
